Injured TE Byham waived; Aldon Smith, Brooks, Cox, Walker still out

The 49ers have waived injured tight end Nate Byham, who entered training camp as a candidate to secure the No. 3 job behind Vernon Davis and Delanie Walker.

Byham missed last season after tearing an anterior cruciate ligament in training camp. He hadn’t practiced the past two weeks after apparently aggravating that injury.

Vying for the No. 3 role at tight end are Konrad Reuland, Garrett Celek, newly signed Joe Sawyer and converted defensive lineman Demarcus Dobbs, who may have the best shot if he continues to show two-way versatility.
